Application fi1ed Ju1y 18, 1914. Serial No. 851,804.

To all whom it may concern Be it known that 1,. ROBERT W.' BOWERS a citizen of the United States, residingat York, in the county of York and State of Pennsylvania, have invented a new and useful Closure for Collapsible Tubes and the like, of which the-following is a specification.

The present invention appertains to cloo sures for collapsible tubes and other con- 5 particularl tainers, and aims to provide 'a novel and improved closure device of that nature.

The present invention contemplates the provision of a unique closure device, adapted for use in connection withcollapsible tubes, such as are commonly employed forholding tooth paste, dental cream, mucilage, shaving soap, and divers other priegarations. f

s vention aims to provide a collapsible tube, or other container having a neck provided with a lateral discharge opening or slot, in combination with a cap adjustably or thread- I edly mounted upon the neck to open and close the said opening or slot as the cap is threaded outwardly and inwardly, and without requiring the complete removal of 'the cap to open the passage through the so neck.

A further object of the present invention is to provide means for effectively sealing the tube or container, when the cap is threaded tightly against the shoulder of the tube or container.,

It is also within the scope of the present invention to provide a closure device of the character specified which may be combined with a collapsible tube or other container,

40 which will be comparatively simple, compact, non-.encumbering and inexpensive in construction, which will be neat and attractive in appearance, and which will be simple, convenient, practical and elficient in its use.

With the foregoing and other objects in view which will appear as the description roceeds, the invention resides in the comhination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the inventionherein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention. j

The invention has been illustrated in its a more specific object, the present inpreferred embodiment in drawing, wherein v Figure 1 is a side elevation of a collapsible tube having the improved closure devlce applied thereto, a portion of the tube being broken away, and the closure cap bemg unscrewed to open the passage through the neck.

Fig. 2 is an end view of the tube looking toward the closure device.

Fig. 3 is a cross section taken on the line 33 of Fig. 1.

Fig. 4 is a longitudinal section taken on the line 4-4 of Fig.1.

In the drawing, there is illustrated a container 1, which is in the form of a collapsible metal tube, such as is commonly employed for holding tooth paste, mucilage, shaving soap and other preparations.

The tube or container 1 is provided at one end with a reduced exteriorly threaded neck 2, having the longitudinal passage 2 leading to the interior of the tube or container 1. The tube 1 is provided with a shoulder 3 between the neck 2 andthe body of the tube, and the shoulder 3 is provided with an annular upwardly projecting flange or lip 4L surrounding the basal portion of the neck 2 and forming an annular channel or recess 5, in which is seated a washer or gasket 6. The washer or gasket 6 fits snugly within the flange or lip 4 and around the basal portion of the neck 2 and is preferably composed of several plies of paraffined felt paper, or other compressible material. The washer or packing 6 is flush with the edge of the fiange or rim 4 to provide a neat appearance. The outer surface of the flange or lip 4 is beveled to provide a frustoconical surface growing smaller in diameter from the body of the tube to the edge of said flange or lip, whereby the flange or lip is strengthened, and whereby the tendency for the flange or lip to be bent out of shape is reduced to a minimum.

Theneck 2 is provided with a partition 7 between its ends and adjacent its upper or free end, which closes the outer end of the passage 2*, and the neck 2 is further provided at one side with a narrow longitudinal opening or slot 8 leading from thepassage 2 to the exterior. The slot 8 is elongated, and is disposed longitudinally of the neck at one side thereof. The slot 8 is located between the partition 7 and the inner end of the accompanying the neck, and the outer end -of the slot is flush with the inner side of the part1t1on,

whereby the paste or contents of the tube or container will be properly directed through the slot 8 by the partition 7. The outer end of the neck projects beyond the partition 7 to provide a pocket or concavity 9 at the outer end or mouth of-the neck 2.

A relatively long cylindrical cap 10 is threaded over the neck 2, and is provided intermediate its ends with .an enlarged polygonal portion 11 for enabling the cap 10 to be readily grasped by the fingers and rotated. The lower edge or rim of the cap 10 is provided with an annular head 12, which is 'seatable upon the-washer or gasket 6, when the cap 10 is screwed downwardly over the opening or slot 8.

The upper end of the tube 1 is preferably tapered surrounding the flange or lip 4, as clearly apparent by reference to Figs. 1 and 4. v o

In use, supposing the tube or container 1 to be filled, then, when the cap 10 is unscrewed, as seen in Figs. 1 and 4, the opening or slot 8- will be-uncovered, it not beingv necessary to completely unscrew or to detach the cap 10 from the neck 2. The tube 1 in being compressed or rolled, will eject the contents through the opening or slot 8, in the form of a ribbon, in order'that the contents may be readily discharged and applied to a tooth brush, or the like. Itwill e observed that the contents being discharged through the opening or slot 8 of the neck, is of advantage, inasmuch as the employed.

neck 2 may be Imsitioned' transverselyover I the bristles of a tooth brush, and then moved longitudinally of a tooth brush, to convene iently-apply the tape or'ribbon of tooth paste or cream thereto, supposing the same to be To close the opening or slot the cap 10 is threaded down or inwardly upon the neck 2, the inner end or head 12 of the cap bearing snugly and tightly against the washer or v gasket 6, to tightly seal the passage through the neck.

Insome instances, the walls of the opening or slot 8 may be parafiined, -or similarly treated; toenable the contents to pass through the opening or slot'S, without stickmg or-clinging to the walls thereof, as might tend to gum the threads of the neck and cap, as the cap is adjusted upon the neck.

From, the foregoing, taken in connection with the drawing, the advantages and ca-- pabilities of the present device will be ap- Witnesses: parent, without further comment being necessary. i 1

Particular attention is directed to the fact that the cap 10 need not be detached or completely unscrewed from the neck 2, to open the passage through the neck,-and which reduces to a the possibility of mislaying or losing the cap, and which also in-' creases the convenience oof'the closure dethe inner side of the partition 7, causes the paste or contents of the tube to be properly directed out through the slot 8, without the liability of waste paste or material lodging within the neck so that it cannot be ejected. The'partition 7 being located between the ends ofthe neck whereby the outer end of the neck projects beyond the partition, enablesthe cap 10 to be unscrewedabove or beyond the slot 8 and partition 7, without completely detaching the cap, and furthermore, the cavity 9 will provide an auxlliary air chaniber between the neck and cap, which will enable the air to expand and contract properly within the cap, when the cap is unscrewed and screwed tight, respectively, and if the cap is engaged so tightly to the neck as to prevent the air from passing between the neck and cap when the cap is threaded up and down upon the neck.

Having thus described the invention, what is claimed as new is:- a

A collapsible tube having a reduced neck at one end, a shoulder between the neck and body of the tube, and an annular flange sur-' rounding the basal portion ofthe neck, the outer surface of the flange being beveled to provide a frusto-conical surface growing smaller in diameter from the body of the tube to the edge of the flange, the neck having a narrow longitudinalslot at one side' and 'a partition therein flush with the other end of said slot, the neck and inner surface of. said flange being perpendicular with said shoulder, a gasket fitted snugly within said flangearound the basal-portion of the neck flush with the edge of-said flange, and a cap threaded onto the neck and seatable against thegasket. I

In testimony that I claim the'foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
